Patent number: 4164117Abstract: A method for producing ingrain spun-like yarn simulating a blended staple yarn is described wherein continuous filament yarn is produced which has characteristics similar to blended staple spun yarns. Fabrics made from the yarns described herein provide a fine grained heather appearance without the normal moire or plaiting effect seen in previous ingrain continuous filament yarn fabrics. The unusual continuous filament yarn described herein is made by a texturing process which involves the combination of two or more differently dyeable continuous synthetic yarns which are false twist textured followed by overfeeding to an air bulking means. The preferred method utilizes false twist texturing of synthetic filaments such as polyester, nylon, cellulose acetate or cellulose triacetate and mixtures thereof wherein two differently dyeable yarns are combined with an air bulking jet interposed to act on the false twist textured yarn while it has a high residual torque and subsequently decaying said torque.Type: GrantFiled: October 6, 1977Date of Patent: August 14, 1979Assignee: Fiber Industries, Inc.Inventor: James R. Talbot

Patent number: 4137976Abstract: The total weight of fibrous material delivered to a packaging device, such as staple textile fiber delivered to a baling press, is controlled so as to facilitate achieving more uniform package weight in accordance with a method and through the use of an apparatus in which material is successively accumulated into batches, each of which is a fractional portion of a desired package weight. Batches are accumulated and released as the actual weight of each delivered batch is determined and registered and the registered actual weights of the successive batches are totaled. The weight of at least certain batches in the succession is then adjusted in such a manner as to closely control the total weight. A weigh container having an inlet and an outlet is interposed between and operatively communicates with a source of supply of fibrous material, such as a tow cutter, and a packaging device, such as a baling press. A load cell is provided which signals the weight of material supported by the weigh container.Type: GrantFiled: May 9, 1977Date of Patent: February 6, 1979Assignee: Fiber Industries, Inc.Inventor: Allen M. Grayson, Jr.

Patent number: 4134248Abstract: An apparatus and method is provided for the placement of a heat-shrinkable film over the open portion of a container such as a glass, paper or plastic cup. The apparatus is particularly suitable for rapid placement of a heat-shrinkable film on food and beverage containers such as are commonly used in the fast-food service business. The apparatus comprises a film transport subsystem for withdrawing heat shrinkable film from a supply roll, cutting the film to size and positioning it for shrinkage onto a container and a heating subsystem which shrinks the film onto the top of a container. Operation of the apparatus is initiated by manual placement of the top of a container to be covered, against the film, pushing the container and film upwardly into the apparatus. The upward movement of the container engages the film and container top with a bonnet which initiates blowing of hot air of heat shrinkable temperatures to heat the exposed edges of the film and shrink the film onto the container.Type: GrantFiled: May 10, 1976Date of Patent: January 16, 1979Assignee: Kup Kap, Inc.Inventor: Warren R. Freeman

Patent number: 4000238Abstract: An apparatus and a method is disclosed for the production of synthetic filament yarns containing substantial portions of additives which retain or develop a stickiness under certain yarn spinning conditions. Such additives cause the individual filaments in the yarn to adhere to each other under hot, humid spinning conditions such as are countered more particularly in nylon spinning-steam conditioning. The apparatus disclosed is a convergence guide which brings the filaments together in the spinning column just prior to the steam conditioner, but in so converging the filaments, maintains the individual filaments in a spaced relationship to each other such that they remain separate from each other as they pass through a steam conditioner.Type: GrantFiled: November 1, 1973Date of Patent: December 28, 1976Assignee: Fiber Industries, Inc.Inventor: Charles Jay Maurer

Patent number: 3975488Abstract: There is provided a process for preparing yarn comprised of at least 83 percent (by weight) of poly(tetramethylene) terephthalate with a spun denier per filament of from about 0.6 to about 50 from a polymer with a relative viscosity of from about 10 to about 50. In said process filaments of said polymer are extruded through a spinnerette at a spinning temperature of from about 240 to about 280 degrees centigrade, and the extruded filaments are taken up at a windup speed of from about 1000 to about 10,000 feet per minute; during said extrusion, the spinning threadline tension per extruded filament (as measured about 70 inches from the face of the spinnerette) is at least 0.09 grams per filament. Thereafter the extruded filaments are drawn in one or more stages to a draw ratio of from about 1.0 to about 5.0 and, during the drawing step, the filaments are passed over a heated object at a temperature of from about 60 to about 180 degrees centigrade.Type: GrantFiled: April 19, 1974Date of Patent: August 17, 1976Assignee: Fiber Industries, Inc.Inventor: Joseph H.

Patent number: 3969462Abstract: A method and apparatus are disclosed for the production of a novel industrial polyester filament yarn of improved uniformity wherein a plurality of filaments are melt-spun into a heated zone coupled with controlled cooling. The yarn produced has improved long and short term Uster uniformity and improved uniformity of physical properties, particularly breaking strength, as shown by a reduced standard deviation of breaking strength. The yarn is produced by melt spinning into a heated zone which maintains the filaments molten for intervals below the spinneret face and subsequently quenching the filaments with a radial outflow of cooling gases, thereby producing a low birefringence yarn which is capable of being drawn at high draw ratios to high tenacities.Type: GrantFiled: November 7, 1974Date of Patent: July 13, 1976Assignee: Fiber Industries, Inc.Inventor: Richard H. Stofan

Patent number: 3957601Abstract: A method for the direct extraction of metal values from subterranean sulfide ore deposits is described utilizing electrochemical techniques. The method eliminates the physical digging and crushing of ore. The process can be controlled to extract only the metal values and other useful chemicals from the earth deposit, thus reducing waste disposal and environmental pollution problems. The prior art difficulty with polarization of the electrodes is overcome by utilizing electrolytes of high halogen ion content, thus eliminating insulating sulfur buildups and permitting economical usage of higher current densities.Type: GrantFiled: May 17, 1974Date of Patent: May 18, 1976Assignee: Mineral Research & Development CorporationInventors: William F. Drinkard, Jr., Henry S. Brown
